Cryptsetup 2.7.5 Release Notes
==============================
Stable bug-fix release.

All users of cryptsetup 2.7 must upgrade to this version.

Changes since version 2.7.4
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Fix possible online reencryption data corruption (only in 2.7.x).

   In some situations (initializing a suspended device-mapper device),
   cryptsetup disabled direct-io device access. This caused unsafe
   online reencryption operations that could lead to data corruption.
   The code now adds strict checks (and aborts the operation) and
   changes direct-io detection code to prevent data corruption.

* Fix a clang compilation error in SSH token plugin.

   As clang linker treats missing symbols as errors, the linker phase
   for the SSH token failed as the optional cryptsetup_token_buffer_free
   was not defined.

* Fix crypto backend initialization in crypt_format_luks2_opal API call.
